[PATCH 19/34] brcmfmac: Get rid of chip_priv and core_priv structs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is zero need to keep these structures separate, they are *always*
allocated together. All they do is obfuscate the code, whilst offering
zero real gain.
